Adjacent Construction: Mitigating Concerns for Nearby Structures in Dense Urban Areas

Adjacent Construction: Mitigating Concerns for Nearby Structures in Dense Urban Areas

Construction performed in dense urban environments like New York City can create serious effects on surrounding buildings and infrastructure. To minimize the risk of damage to adjacent structures, project teams must mitigate potential issues with protections and controls. These measures range from simple safety steps to very complex installations requiring specially engineered systems. In this presentation, we will explore typical and atypical risks associated with construction operations on adjacent buildings and review protections required under the New York City Building Code.


After attending this seminar, participants will be able to:

  • Identify common risks to adjacent structures during construction.
  • Discuss unique situations and concerns affecting adjacent structures during construction.
  • Identify minimum code requirements for protecting adjacent structures.
  • Recognize typical systems and controls used to protect adjacent structures.

Participants will earn 1.0 AIA CES Learning Unit (LU/HSW). While we encourage you to invite colleagues, please note that space is limited. Registration is free.

Nathaniel Smith | Structural Engineering Division Head, New York

Nathaniel’s expertise includes building damage and collapse investigations, repair and rehabilitation of existing buildings including historic structures, and foundation installation monitoring. Nate has worked with numerous long-term clients on projects related to the effects of construction on adjacent structures including pre-construction mitigation and risk assessment, damage assessment, and design of repairs. His background in geotechnical engineering and understanding of soil and foundation types helps inform his structural evaluations of existing buildings and investigations of structural damage and collapse. He believes in the value of life-long learning and has given numerous presentations and authored papers on adjacent construction matters.
